  Natural Waters are normally Considered as Healthy, and most of the sources of pollution such as heavy metals, get Through the water, during the passage to reach the consumption aera. Therefore to search the total pollution, sampling was performed from the tap water (7 stations in Tehran). Samples were analyzed to determine the concentration of the elements such as Pb, Cd, Ni, Zn and Cr. Comparison of the results with that of the EPA Standard values showed that the concentration of Pb were much higher in few stations. Considering the canceriogenic effects of Pb, this can be very hazardous. There were no problems due to the other elements, One of the sources of Pb uptake is the piping network system, sharing 29% which seems to be the main source. However reduction and removal of heavy metals were examined by the Reverse Osmiss method at the second step. The results showed high reduction and removal of Pb by this method, so the method looks to be very applicable./s
